While in cruise control, the car suddenly reduced its speed; there is no obstacle in the path of the cat that would warrant such an action. This deceleration is sudden and violent and when it happens is dangerous for following drivers.
2023 Tesla Model 3 driver assistance complaints
Page 7 of 8: complaints 161 to 190 of 198, newest first, as owners wrote them.
On a clear sunny day driving on the freeway at 75mph on a 70mph speed limit, the regular cruise control(not Autopilot) was engaged. Experienced 4 separate incidents of strong emergency brakes being activated by the vehicle automatically for 2-3 secs, dropping speed by 10-15mph. As the driver I disengaged the cruise control by strongly accelerating the vehicle. Also multiple incidents of brakes engaging slightly for 1 second , always when driving on a straight freeway, with zero other vehicles present in the front or rear. The road had a slight incline then a slight decline. Just as the vehicle reaches the top of the incline the brakes activated. No warning lamps of sounds, just immediate sharp braking one all incidents. As the driver I felt very unsafe, and glad there were no vehicles close behind, which could have resulted in a rear collision. Vehicle has not been inspected by any party. As a Tesla driver I do not trust the Standard Cruise control feature any more.
2023 Tesla Model 3- Consumer wrote about comparison of braking mode to non-EV's, experience driving a rented EV (Electrical Vehicle) w/ braking mode and suggestions to make EV's braking mode safer. When EV's accelerator is NOT pressed the EV goes into regenerative braking mode. No brake lights are triggered because brake pedal wasn't pressed. Consumer listed two "real world dangers". Consumer recommendation- The regenerative braking of EV's should also trigger brake lights notifying vehicles behind the EV that the pace of the vehicle is slowing with the same force. as if brakes where applied.
Vehicle breaks suddenly for no reason under a variety of circumstances. there is no pattern I could identify. i went on line to see if there is an update. many others with the same problem. Very dangerous if there is a car behind. Happens every day or so at freeway speed. Tesla needs to fix this!
When driving and using “autopilot” or just cruise control, the vehicle will randomly brake. Sometimes it brakes lightly, but sometimes it will violently slow the vehicle down, without warning. There is no obstacle in front of the vehicle. If another vehicle is behind the car when the car randomly brakes, this can potentially cause a rear-end event or potentially cause the car that is behind to swerve to avoid an accident. I submitted a service request to Tesla, but Tesla responded by stating that there was no malfunctions that needed to be addressed. They described various scenarios in which the computer would determine a need to brake.
Phantom braking. Traveling highway 5 Southbound between Red Bluff, CA and WIliams, CA at 70 mph, the vehicle suddenly and firmly applied brakes as if attempting to avoid a collision with an obstacle closely ahead. The braking force was enough to activate the seatbelt restraint. There was no traffic for at least a 1/4 mile ahead and behind and no obstacle. I managed to flip the ACC lever up to disable it during the braking but felt that I was losing control of the vehicle. After ACC was disabled normal operation ensued. Speculation: The incident occurred mid-May and the area is agricultural and therefore teeming with bugs that collect on the front of the car. The forward camera may have been hit by a bug and the visual recognition system may have mistaken the bug for a large obstacle.
Tesla 3 2023 is making hard breaks on auto pilot even though there is no objects. It’s happened over 30 times in last 7 days. It’s scary bcz other cars Coming behind can leads to life threatening accidents. Pls help
The contact rented a 2023 Tesla Model 3. The contact stated that while testing the collision avoidance system the vehicle was moving at 2 mph and the brake pedal was not depressed the collision avoidance system did not activate. The vehicle collided with another vehicle. The air bags did not deploy. A police report was filed. The manufacturer was notified of the failure. The failure mileage was approximately 30. The VIN was not available.
Car steering felt stuck and slid off the road which resulted in crashing into a tree. Tesla features did not help stay in the lane or break in an emergency.
Hello, I have experienced 2 times the same issue with this new car model. I was driving on a interstate with 2 lanes, no cars in front of me and fortunately no cars behind, I was in autopilot mode and emergency brake system got engaged for no reasons apparently (Phantom braking) and I had to take over immediately. It was scary and I was lucky that no car was behind as it could have created definitely a worse scenario. The first time I was entering a bridge and the color of the asphalt was a bit different from the main road that might have triggered this phantom braking. The second time I entered in a driving area in the shade, here the phantom braking might have been triggered by a sudden change in the sun light. Regards.
The vehicle gives false forward collision warnings which increases my insurance premium. This happened multiple times in the last month.
The car phantom brakes 50% of the time when I use Enhanced Autopilot Feature on the highway
Automatic emergency braking. Phantom braking without any real incident
At random times the vehicle will slam on the brakes although there is nothing in front of it. It has happened with vehicles behind me and I have averted multiple crashes by luck I suppose.
I was driving on the HOV lane (going between 65-70 miles mph) with the adaptive cruise control and lane keep assist on when the car suddenly slammed on it’s brakes to stop. There was a slight hump in the highway, but no car or object in front of me in the lane. Thank goodness there were no cars behind me or they could have easily rear ended me. It was extremely scary and now I’m too scared to use these driver assist features moving forward.
I was on Interstate I5 on March 16th with car cruising on Tesla Auto Pilot Assist. The road was completely clear with nothing ahead of behind me for atleast half a mile. All of a sudden I experienced Sudden Breaking (Phantom Breaking) and broke hard to about 30 MPH before resuming. I was fortunate that there was nothing behind me otherwise I would have been rear ended. The only thing I could see was there as a dip in the roadway and some shadows were falling across the highway. Tesla has no radars and I suspect the camera was fooled by the lighting.
I bought a new Tesla Model 3 in December of 2022. In mid March 2023 we had our first road trip in this vehicle. I had at least 4 major phantom braking incidences while traveling an average of 75 mph on I-80 with the cruise control on. Two were experienced while traveling eastbound in Nebraska and two were while traveling westbound a week later in Wyoming. Each experiece was separated in time by at least two hours. The last one scared me and my wife so much that she won't ride in the Tesla on the freeway until it is fixed. We also had several minor phantom braking experiences which did not alarm us. What happened is that the car slammed on the brakes while going 75 and reduced the speed to about 55 in seconds. It was over before I could react. The tires did not skid and fortunately no one was following us. I fear that if someone was tailgating me that they would have rear ended our car. I had experienced a couple of phantom braking events in Utah in previous months but they weren't severe enough for me to report it.
- The adaptive cruise control malfunctioned, It sharply braked while no cars in front or arround me was braking.Conditions were clear, no rain/no snow, in the daytime. The windshield was clean, the road was clean as well (on the asphalt with road markers clearly visible). - My safety and the safety of others was put at risk, the braking was realy sharp nothing could have helped me or other users of the road predict that it was going to happen. Someone behind had to slam the brakes to avoid a collision with me. - Nothing was inspected - No warning or symptoms were visible then nor now.
While traveling with cruise control enabled and not using autopilot, about every 50 miles or so I will encounter a situation where there is no one in front of me and the car with begin rapidly decelerating. I have had several drivers behind me hit their horns in a panic while trying not to hit my car. I am very worried that this issue will cause me to be rear-ended by another driver. This issue is occuring at both highway speeds exceeding 65mph as well as speeds speeds as low as 50 mph. It has happened on multi-lane highways with no other cars around as well as on single lane local roads.
I experienced unnecessary emergency braking while driving from Chicago to Madison on I-90. I was driving at 75 mph on adaptive cruise control with auto steer on. I suddendly I experience hard braking for no reason. I observed my set speed limit changed to 45 mph. However, I instantaneously took over and pressed accelarator. I experienced the same 2 more times during the same trip. It's created a very dangerous situation.
Driving on interstate using Tesla model 3 autopilot about 75 mph. Road narrowing from 3 to 2 lanes and I was in the merging lane approaching entry to 2 lane road. Cars were to my right, visible, but safely distant. Suddenly, unexpectedly the car started breaking, creating alarm for me, but was able to re-engage the accelerator and safely merged into 2 lane highway. If a car was closely following me, which was not the case, could have resulted in rear end crash. Had used autopilot frequently before this episode and never had this problem, and subsequently autopilot seems to be working properly. Occurred 3/11/2023.
The undercarriage shield of my car disconnected and started dragging while I was driving in the rain. I did not collide into anything or hit a bump. I inspected my wheel well to discover a set of screws that were bunched up and not installed during manufacturing. I had to pull the shield from under my car so that I can continue to drive the vehicle. the shield is connected to the forward warning and pedestrian warning collision system which became inoperative. The faulty manufacturing that caused the shield to disconnect caused a dangerous condition while operating. After I removed it, a second dangerous condition was created since all of the safety senors were disconnected.
We were driving down the road, emergency braking enabled came on and car came to a complete abrupt start 10ft from railroad tracks and would not do anything. Could not reset it. Nothing.
This model doesn't have parking assist, so every time I park there is a danger of collision. All modern cars have parking assist. Tesla promised in Nov 2022 that software update enabling parking assist will be available within "next couple of weeks". 3 months passd since then and there is still no parking asist.
Multiple times on the highway the car would slam the brakes for no reason in autopilot mode reducing the speed significantly. In all cases it reduced the speed from around 70 mph to 40 mph. The road was clear with no vehicles in front.
My Tesla Model 3 was delivered on 14 December 2022. I first drove it on 16 December 2022 and that day I had an accident. I was about to park my car and I was already on the designated parking slot when the car made a sudden Un- commanded acceleration. I first hit the handicap sign, but the car did not stop and apparently the collision avoidance safety feature did not work. The continue to accelerate and I hit a restaurant establishment. The police came and I reported the incident to my insurance (Geico). The police (Mr. McClure) gave me the case number 2238293. Geico is taking care of the repair which would cost over $10K and the property damage, which added up to 10K. I went to the Tesla service center in Carlsbad and Mr. Hyuma said that I can request for the log. I guess it is the EDR. They gave me a link to request for the EDR but the start date is 23 January 2023 way after the accident date of 16 December 2022. I have not received any log or EDR from Tesla to date. I am uploading the pictures of the car before the repair. Please help me find out what exactly happened and why the car suddenly accelerated without pressing the gas pedal. I am a retired US Navy (20 years) and I bought a Tesla to save money because i have solar in my house. I have a fixed income and cannot afford to spend money on the EDR. I believe that here is a defect on the Tesla Model 3 that I bought and I will appreciate all the help you can provide.

The manufacturer was notified of the failure and filed a case. The failure mileage was 8,728.
While exiting a hospital parking deck, after driving for approximately 15 to 20 seconds, the car began to accelerate to an uncontrollable rate of speed on its own. The Tesla crashed into a parked car which was then pushed into two other parked cars. The Tesla and at least the first car hit are totaled. There was no sign of the emergency braking system engaging. Injuries from the airbag deploying were sustained. The driver has a fear to drive again as the car seemed to have a mind of it's own. The Tesla is being held at the insurance company's tow yard. There has been no feedback from the dealer. No inspections have been conducted on the car. There were no indications there was a problem with the vehicle previous to the crash. It is unknown if any warning alert systems activated during the incident.
This model has misleading user manual about park assist chime button, park assist front camera on button. Apparently they have removed the ultrasonic sensor and did not enable any user interface to do with Park assist in the control menu. This is misleading safety feature and total lie to the customer. Please flag this as a safety flag so the user will be aware of it. There is no option for the user to enable the front camera for whatever the little useful it can offer. They need to immediately send us the software update to view any camera at will.
